Not really sure if this is the proper forum, but I didn't see where else to ask about AC components.

What is the secret for safely removing, i.e. without damaging the fittings, the high and low pressure AC lines that connect to the evaporator coil in front of the radiator? I am going to see if my friend can bleed my system and then I want to remove these lines to gain full access to my core support. Looking at them, they remind me of brake lines, which often bend, since the nut tends to get corroded to the pipe itself and applying the necesary force to beak it free ends up turning the line into a Twizzler.

Thanks for any guidance.

 

they're not near as bad as brake lines. it's a very good idea to bleed the pressure before you take a line apart. you do want to use flare wrenches and support both lines so you don't put a kink in them.

 

Thanks a lot for the reply.

Hopefully, then, they'll come off nicely. Worst case scenario, I break one and have to get a replacement, I suppose. But, I would like to avoid that if at all possible! Too bad they are made out of aluminum and not a stiffer/stronger metal.

 

try taping on the lines with a hammer gently but keep another hammer oposite from the one u r taping with that will help lossen up the threads good luck!!

 

Well, the low pressure line came apart without too much of a fight. The high pressure would not budged, and ended up snapping off. After it came off, I looked at where the aluminum line passes through the fitting, and it was clear that they were corroded together pretty badly. Oh well, what can you do sometimes?
